TYPE-WRITING MACHINE.

Specification of Letters Patent.

Patented June 14, 1910.

Application filed September 21, 1906. Serial No. 335,616.

To all whom it may concern:

Fig. 3 is a side elevation of a sliding stop Be it known that I, LEE S.BURRIDGE, a 1 provided with graduated push rods or fincitizen of theUnited States, residing in the borough of Manhattan, city, county, andState of New York, have invented certain new and useful Improvements inTypelVriting Machines, of which the following is a specification.

This invention relates to the tabulating mechanisms of typewritingmachines.

The principal object of the invention is to simplify and improve themeans for arresting the letterspacing carriage of a typewriter at anyselected denominational point, and particularly to render the operatorscontrol of the carriage more certain and convenient.

In carry-ing out the invention, I provide a carrier to swing or moveacross the machine in front of the keyboard, and upon the carrier Imount denomination-selecting devices. This carrier is caused to movewith said letter-spacing carriage, by means of suitablemovement-transmitting mechanism pivoted upon the framework of themachine and connected to both the carriage and the carrier. In thisinstance, the movement-trans- Initting mechanism is in the form of alink age, which causes the carrier to have a parallel motion in astraight line across the machine, although othermovementtransmitting-mechanism may be employed for the purpose.

The denomination stop mechanism herein illustrated comprises a series offinger-pieces or push rods of graduated lengths, and connected to agraduated stop, means being provided for arresting the finger as soon asthe stop corresponding to the fi11gerpiece that is operated is adjustedto position to cooperate with a column stop mounted upon the frameworkof the machine. Said fingerpieces are shown projecting differentdistances through a plate which forms part of a carriage-releasingmechanism, and is arranged to be moved by the finger a limited distancefor releasing the carriage during the last part of each stop positioningmovement.

Other features and advantages will hereinafter appear.

In the accompanying drawings, Figure 1 is a sectional elevation takenfrom front to rear of a Sun typewriting machine showing my improvementsapplied thereto. Fig. 2 is a rear elevation of the machine.

F 5 leasing platewith the denomination-selecting finger-pieces projecting therethrough.Fig. 6 is an inverted plan of the graduated stop member seen inelevation at Fig. 3.

In said Sun machine, the types strike rearwardly against the front sideof a platen 1, which is mounted upon a carriage 2 traveling upon balls 3across a framework 4, and pivoted with a letter spacing rack 5, engaginga pinion 6, the latter connected to an escapement wheel 7 provided withany usual escapement devices 8. Said framework includes a rectangularbase 9 having the usual front keyboard 10 and resting upon feet 11.

Mounted upon the front bar 12 of the base by means of studs 13 is a rack14 along which is adjustable a column stop 15, of which several may beprovided, said stop having a pendent tooth 16 to engage any one of aseries of steps 17 formed at letter-space intervals upon a stop-member18, which is mounted upon a carrier 19, the latter arranged at the frontof the keyboard and below the framework of the machine, and de signed totravel across the machine together with the carriage 2. Said carrierisillustrated in this instance in the form of a long bar extending fromthe keyboard back under the framework to the rear of the machine. It ismounted for a parallel motion upon the ends of two levers 20, 21, whichare suitably connected to the framework of the machine and to eachother.

22 designates the pivotal connection of the forward end of the bar 19 tothe forward end of the lever 20, and 23 indicates the pivotal connectionof the rear end of said bar to the rear end of the lever 21. The latteris fulcrumed at 24: upon a bridge 25 extending across the base, and therear end of the carrier bar 19 isslot-ted at 26 to accommodate theswinging movement of 23 about the axis 24:. Said levers 20 and 21 may beconnected between their ends in any suitable manner to cause their frontand rear ends respectively to move in unison from side to side of themachine. For instance a link 27 at the beginning of a line of is a frontelevation of a carriage-1e 'may be pivoted at 28 to the lever 21 and at29 to an offset portion 30 formed upon the lever 20. By means of saidconnectedlevers, the bar 19 is caused to have a parallel mo tion acrossthe machine.

in order to cause the pivot 22 upon the front end of the lever 20 tofollow a straight path across the machine, a pin 31 is provided upon thelever 21 to engage a slot 82 formed in the lever 20, said slot beingcurved in such a manner as to produce the desired straight line motionof the pivot 2. The rear end of the lever 20 may be pivoted at upon theend of an idle link 84 pivoted at upon the framework 9. Since the pivotof the lever 20 moves in a straightline, it guides the carrier 19 in astraight path across the machine, so that the proper cooperation is madepracticable between the column stop 16 and the various stepped stops 17.

The graduated stop-member 18 is mounted upon a base 36, which by meansof two shoulder screws 37 is guided in backward and forward slidingmovements in a slot 88 formed in the frontend of the carrier 19, wherebyany of the steps 17 may be set back to position to engage the stationarycolumn stop 16 upon the release of the carriage.

Upon the front of the plate 18 is provided a vertical flange 89 in whichare fixed push buttons or finger-pieces 40 preferably arranged.alternately in two rows, Fig. 5, so as to give room for manipulation andbeing of graduated lengths. All of said push rods 10 project throughholes formed in a vertical plate 41 extending in front of the flange 39.This plate is formed by bending up the front end of a bar 42 whichslides at its rear end upon a screw 13, and is supported in front bysaid rods 40. Said bar 42 is formed with a rear lip to press backwardlya horizontal bar 45 extending across the machine and having at its endsarm 46 forming a bail, which is secured upon a transverse horizontalrock shaft 417. The function of said transverse bar is to release thecarriage; one of said arms 46 being lengthened at 418 and connected by alink e9 to an arm 50, pendent from a horizontal transverse rock shaft51, the latter carrying an arm having a finger to engage the cscapementdevices 8, and force the latter out of engagement with the escapementwheel 7, whereby the carriage is released, and may run for ward freelyunder the influence of its driving spring 54, the latter connected tothe carriage by a strap 55, Fig. 5. The movement of the carriage iscommunicated to the carrier 19 by means of an arm or frame 56 into thelower end of which is threaded at 57 the screw 23 of the parallel motionmechanism. Said arm 56 is hinged at 58 to the carriage so that the lowerend thereof may swing out to accommodate the curvilinear movement of thescrew 23 about the axis 24. Whenever any of the finger pieces 10 ispressed forwardly by the finger, the stopmember 18 is thrust back andduring the last part of such movement the finger engages the carriagereleasing plate 41, and moves back the same together with the slidebar12 and transverse bar 45, thereby releasing the carriage. The plate 41is arrested in its backward movement by engagement of the front end of aslot 59 with the screw 48, Fig. 4:, and this determines the ex tent ofdisplacement of the stepped stop member 18 from normal position, andhence, which of the stops 17 shall be brought to position, to engage thecolumn stop 16. If the extreme left hand button 40 at Fig. 6 is selectedand pushed back, the movement of the member 18 would be least, and theextreme left hand stop 17 would be positioned to engage the stop 16.Upon the other hand, if the extreme right hand push rod 40 is operated,the plate 18 would be given an ex treme movement, and the extreme righthand one of the set of stops would be brought into position to engagesaid stop 16; while any of the intermediate stops 1? may be brought intouse by operating its corresponding push rod or key 40. The carriagereleasing mechanism is returned to normal position by a spring 60, andthe stop member 18 is returned by a spring 61. The carriage 2 shifts upand down to enable different types to print.

The carriage track frame 62 shifts up and down upon ball-bearings (38,Fig. 2, as usual in the Sun machine, and it will be understood thatthere is sutlicient play or yield at the joint between the lever 21 andthe bridge 25, as well as at the other joints of the parallel motionmechanism to accommodate the up and down shifting of the carriage 2,which is very slight.

It will be seen that owing to the arrangement of the denomination stopcarrier at the keyboard, the operator can very conveniently control themovements of the carriage both for tabulating work, and also for re--turning the carriage to begin a new line, or otherwise manipulating thecarriage; the provision of a carriage releasing member upon the carriercontrolling member 19 at the front of the keyboard being a greatconvenience.

Variations may be resorted to within the scope of my invention, andportions of my improvements may be used without them.
